ROBERT G. PILKINGTON, OF CHICAGO, ILLINOIS, ASSIGNOE TO DODGE MANUFACTURING COMPANY, OF MISHAWAKA, INDIANA, A

CORPORATION OF INDIANA.

BOTATABLE HEADLIGHT-SUPPORT.

To all whom it may concern:

Be it known that ROBERT G. PILKINGTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, has invented certain new and useful Improvements in Rotatable Headlight-Supports, of which the following is a specification.

My invention relates to improvements in rotatable head light supports and it appertains more especially to the specific details pointed out in the annexedclaims.

The purpose of my invention is to pro vide a support for head lights that shall permit of a shifting of the beam to either right or left, and up or down, without the use of complicated parts; that will utilize the geometric relation of the rotation, of a conical path of light, with respect to the center line of the main support for the purpose of deflecting the beam as desired; to provide means for locking the parts after they'have been adjusted to meet special requirements of roads; and more especially eliminating exact constructional work when a non-adjustable head-light is placed on a flat portion of the body of an automobile, as for instance the dash.

With these and other purposes in view I illustrate in the accompanying drawing such an instance of adaptation as will disclose the fundamental features without limiting myself to the specific details instanced eX- cept as defined in the annexed claims.

Figure 1 is a side elevation, partly in section.

Fig. 2 is a front elevation showing the means for attaching the support to a car body or other surface.

Fig. 3 is a sectional elevation of a sub base.

Fig. 4 is a rear elevation of Fig. 3 partly diagrammatic.

Fig. 5 is an elevation in section of a T bolt fastening.

The support may be formed in the shape of a casting or it may be made of metal s'tampings or constructed in any desired form so long as the center plane of the lamp itself is found at an angle to that of the support.

The dash or other surface to which the lamp is to be attached may be designated, as 1. The base flange 2 is secured to the dash by means of a number of screws 6 Specification of Letters Patent.

which pass through concentric slots 5 into the dash, orthey might pass into a sub base which itself is secured to the dash. If a sub base is used the adjustments of the lamp can be made from the inside of the dash and after the desired position has been secured the parts can be locked from the same side of the dash, as shown in Fig. 3.

In the form instanced in this figure a'flange 9 has tubular extension 10, an outer annular rim 11 against which base flange 2 abuts resting meanwhile on radial flange 2". This flange has slots 5 corresponding to slots 5 of base flange 2. Screws 6 having wing nuts pass through flange 9f and slots 5 thus holding the parts when adjusted. Screws 6 hold the sub base to the dash I. In this form the flange 2 becomes a substitute for flange 2, the parts 3 and 4 being the same in both cases.

lVith certain forms of lamps the structure instanced in Fig. 1 may be made to serve without cutting an opening in the dash similar to that required for the tubular part 10 of Fig. 3. In such an event only a small opening would be made through the dash to accommodate the usual wires for supplying current to the lamp or any other kind of illuminating media.

WVhen the lamp holder is to be used for cars of the package delivery type the lamps are placed on each side of the bonnet and they are secured on the forms the forward end of the package com partment. In such cases the adjustments may be made from the outside by loosening the screws 6' and shifting the base 2 to the right or left as needed to throw the beam of light in the required direction, after which the screws are again tightened and thereafter their adjustment will be retained as long as desired. This simplifies the construction of cars of this type very much because the lamp setting can be changed to accommodate the lack of parallelism that may be found in the two sides of the dash or any other structural differences without having recourse to expensive expedients which would secure the required precision in the relation of the various parts to each other with respect to the ultimate useful direction of the beam from each lamp.

The base 2 usually has a body portion 3 formed integrally therewith. The body 3 has a flange 4 to which the lamp 8, of any dash which usually desired type, is attached by means of screws which pass into suitable holes 7 of the flange f. It will be seen that the means employed for shifting the beam of light is very simple indeed as it is accomplished in a very effective manner by inclining the flange 4 to the base at an angle of about five degrees more orless, as is clearly shown in Fig. 1. If desired I might make the slots 5 of an undercut shape 18 and extend them all the way around and using T head bolts 12, such as are well known in the mechanic arts. With such a construction the lamp could be moved through 360 degrees, however for most cases the limited arc of adjustment shown will be found ample. The slots 5 can however be made longer than shown without their connecting with each other and forming a single slot.

It will be seen that the holder can be placed into practical use with the least amount of preparatory work; that it can be manufactured economically and has a minimum number of parts consequently is extremely simple. The body portion 3 can be made as deep as desired to accommodate various sizes of standard lamps. If an opening is left in the dash the lamp itself can be focussed without taking off the front glass or loosening the casing from the flange 4, thus adding to the convenience of an equipment.

What I claim is, j

1. In lamp supports, a suitable base, an extension projecting perpendicularly therefrom on one side, a flange formed on such extension whose plane is at an angle to the supporting face of the base, a lamp and casing secured on the extension, and means adapted to support the base said means permitting of a rotary movement of the base and lamp thereon on a plane perpendicular to the axis of the base.

2. In lamp supports, a ring shaped supporting member, separate flanges projecting.

from the ring in an inward and outward direction the plane of such flanges being at an angle to each other, one or more curved openings formed in the outwardly projecting flange adapted to have fastening means pass therethrough, and a lamp supported on V the inwardly, projecting flange whereby as the supporting member is rotated on the axis of the curved opening the luminous beam of the lamp is shifted, the extent of such change being dependent on the angular displacement of the two flanges and the magnitude of the movement.

3. A device for adjustably supporting a lamp on a flat surface, consisting of a supporting member having a rear planeface abutting the surface and having a forward lamp carrying face arranged at an angle to the rear face, and means to rotatably attach the member to the support, comprising out.

therefrom, fastening means cooperating with the outer flange, concentric slots formedin the mternal flange, an annular base held by the slots, an extension to such base having one face parallel with the face of the in- V ternal flange and the other face at an angle thereto, a suitable lamp secured to the latter face, and means for adjustably holding the lamp and base in different positions around the axis of the base. 7

In testimony whereof I aflix my signature in presence of two witnesses.
